Fence Calculator
Calculate how much fencing you need based on the perimeter of your project area. Enter length of each side to get total linear feet, number of posts, and estimated material cost.
Please enter your dimensions above to calculate.

Now that you know how much fencing you need, find a local contractor to deliver it.
How the Fence Calculator Works
Enter your project dimensions (length, width, and depth) and select a fence type. The calculator converts your measurements into cubic yards, then uses material-specific density ranges to estimate how many tons to order.
A waste allowance (default 10%) accounts for uneven ground, spillage, and settling. Compaction is applied automatically based on the fence type — angular wood fence compacts more than rounded vinyl fence. The result is rounded up to the nearest half-ton or full ton so your order matches how contractors actually sell.
How Deep Should Fencing Be?
- Driveways:
- 4–6 inches. Use a compactable base layer (crusher run) topped with 2–3 inches of surface fencing. Heavier traffic and soft soil need the full 6 inches.
- Patios:
- Choose a fence height appropriate for your needs. 4ft fences work well for decorative borders, while 6ft provides good privacy.
- Walkways:
- 2–3 inches is usually enough for foot traffic. Use edging to keep the fencing contained, especially with rounded types that tend to migrate.
- Drainage:
- 6–12 inches depending on the application. French drains and dry wells need coarser stone (#57 or cedar fence) at the deeper end of the range.
Why Tons per Linear Foot Varies by Fence Type
A cubic yard of fencing doesn't always weigh the same. The conversion depends on the stone's density, shape, and how much air space sits between the pieces. Angular wood fence packs tightly and weighs more per cubic yard (1.35–1.55 tons) while rounded vinyl fence leaves more gaps and weighs less (1.30–1.45 tons).
This is why the calculator shows a weight range rather than a single number — moisture content, exact particle size, and source quarry all shift the real weight. When in doubt, order toward the high end of the range. A little extra fence is far cheaper than paying for a second delivery.
